Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a slag removal device for wastewater treatment. Background Technology

[0002] Domestic sewage contains a lot of sludge due to its numerous pollution sources and large discharge volume. If the sludge is filtered directly, it can easily clog the filter screen. Therefore, we need to treat the sewage for sludge removal first. Existing sludge removal devices use screens to filter the sludge. However, since the sludge in the sewage is of different sizes, screens cannot filter sludge of different sizes.

[0003] In the prior art, Chinese utility model application CN202220689482.6 discloses a slag removal device for sewage treatment, comprising multiple shells and a funnel-shaped shell. The multiple shells are spaced apart above the funnel-shaped shell. A discharge pipe is connected to the bottom of each funnel-shaped shell, and supports are fixed around the bottom of each funnel-shaped shell. An upper shell is placed above one of the shells, and a feed pipe is connected to one side of the upper shell. Upper inclined plates are fixed inside the upper parts of the multiple shells, and multiple screen holes are formed on each of the upper inclined plates, with the size of the screen holes decreasing from top to bottom. Lower inclined plates are fixed inside the lower parts of the multiple shells. This slag removal device works by pouring the sewage to be treated into the feed pipe, allowing the sewage to enter the shells through the feed pipe and filter the slag through the screen holes on the upper inclined plates.

[0004] While the above-mentioned technical solutions can achieve multi-stage filtration, in actual use, the shell needs to be disassembled when cleaning the filter cake on the filter plate. This makes it impossible to continue the sludge removal work on the wastewater during the filter plate cleaning process. At the same time, the upper filter plate needs to be removed when cleaning the lower filter plate, and the heavy weight of the shell increases the difficulty of removal. As a result, the efficiency of wastewater filtration needs to be further improved. Therefore, we need to propose a sludge removal device for wastewater treatment. Utility Model Content

[0005] The purpose of this utility model is to provide a sludge removal device for sewage treatment. By setting two sets of detachable mechanisms on the outside of the housing and installing different filter screens in the detachable mechanisms, multi-stage filtration can be achieved without affecting the continuous filtration of sewage, thereby improving the filtration effect of sewage and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sludge removal device for wastewater treatment, comprising:

[0007] The housing, and two sets of detachable mechanisms installed on one side of the housing, each set of detachable mechanisms is equipped with a filter screen for water filtration, and the number of filter holes in the two sets of filter screens increases sequentially from top to bottom;

[0008] On the other side of the housing, there is an anti-stacking mechanism to agitate the space above the filter screen, which is used to move the filter screen to remove impurities.

[0009] Preferably, the detachable mechanism includes a fixed frame and a sealing plate fixedly connected to one side of the fixed frame. The inner side of the fixed frame is provided with a sliding groove for inserting the filter screen plate. The fixed frame is provided with a slot on the side opposite to the sealing plate.

[0011] Preferably, one side of the box body has an installation groove for installing the sealing plate, and the inner cavity of the box body has a support groove for inserting the fixing frame.

[0012] Preferably, a first inclined plate is fixedly connected to one side of the inner cavity of the box, and the first inclined plate is located directly below the water inlet pipe. A second inclined plate is fixedly connected to the other side of the inner cavity of the box, and the second inclined plate is located between two sets of filter screens.

[0013] Preferably, the anti-stacking mechanism includes a mounting frame fixedly connected to the other side of the box. Two sets of rotating shafts penetrating the box are rotatably mounted on the mounting frame. Multiple sets of rubber rods are provided on the outer side of one end of each set of rotating shafts inside the box.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model mainly utilizes the cooperation between the detachable mechanism, the filter screen, and the housing. The detachable mechanism can be disassembled independently. When the upper detachable mechanism is removed, it is convenient to clean the upper filter screen. At the same time, the filter screen in the lower detachable mechanism can continuously filter impurities from sewage. Conversely, when cleaning the lower filter screen, sewage can be filtered through the upper filter screen, thus improving the efficiency of sewage impurity removal.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a slag removal device for sewage treatment, comprising:

[0026] The housing 1 and two sets of detachable mechanisms 5 installed on one side of the housing 1, and each set of detachable mechanisms 5 is equipped with a filter screen 12 for water filtration, and the number of filter holes in the two sets of filter screens 12 increases from top to bottom.

[0027] On the other side of the housing 1, there is an anti-stacking mechanism 4 that agitates the space above the filter screen 12. The anti-stacking mechanism 4 is used to agitate the filter screen 12 to remove impurities.

[0028] The detachable mechanism 5 includes a fixed frame 51 and a sealing plate 52 fixedly connected to one side of the fixed frame 51. The inner side of the fixed frame 51 is provided with a sliding groove 54 for inserting the filter screen plate 12. The fixed frame 51 and the sealing plate 52 are provided with a slot 55 on the opposite side. One end of the upper surface of the filter screen plate 12 is fixedly connected with a lever 13 that is engaged in the slot 55. One side of the sealing plate 52 is fixedly connected with a handle 53.

[0029] In this embodiment, the handle 53 facilitates the removal of the fixing frame 51 on the sealing plate 52 from the support groove 11, and the filter screen 12 is loosened by pushing the lever 13 so that the filter screen 12 can be removed from the sliding groove 54 in the fixing frame 51 by the lever 13. During the removal process, the fixing frame 51 can scrape off the impurities on the filter screen 12, further improving the cleaning efficiency of impurities.

[0030] A water inlet pipe 2 is provided on the upper surface of the box 1, a drain pipe 3 is provided on the lower end of the other side of the box 1, and a drainage bottom plate 9 for water diversion is provided at the bottom of the inner cavity of the box 1.

[0031] The inlet pipe 2 and outlet pipe improve the flow of sewage, and the drainage base plate 9 facilitates the flow of sewage to the drain pipe 3, thereby improving the collection efficiency of filtered water.

[0032] The box body 1 has an installation groove 10 for installing the sealing plate 52 on one side, and a support groove 11 for inserting the fixing frame 51 into the inner cavity of the box body 1. The installation groove 10 facilitates the insertion of the sealing plate 52, and the depth of the installation groove 10 is less than the thickness of the box body 1. At the same time, the support groove 11 supports the fixing frame 51, thereby ensuring the stability of the fixing frame 51. The height of the fixing frame 51 is less than the height of the sealing plate 52, so that when the fixing frame 51 is pulled out, the filtered impurities can be scraped flat through the installation groove 10, thereby facilitating the cleaning of impurities.

[0033] A first inclined plate 7 is fixedly connected to one side of the inner cavity of the housing 1, and the first inclined plate 7 is located directly below the water inlet pipe 2. A second inclined plate 8 is fixedly connected to the other side of the inner cavity of the housing 1. The second inclined plate 8 is located between the two sets of filter screens 12. The first inclined plate 7 can buffer the sewage entering the housing 1, thereby preventing the sewage from directly impacting the filter screens 12 and improving the service life of the filter screens 12. The second inclined plate 8 can buffer the water diverted by the first inclined plate 7 when the upper filter screen 12 is removed for cleaning, thereby reducing the impact force of sewage on the lower filter screen 12 and further improving the service life of the lower filter screen 12.

[0034] The anti-stacking mechanism 4 includes a mounting frame 41 fixedly connected to the other side of the housing 1. Two sets of rotating shafts 42 that penetrate the housing 1 are rotatably mounted on the mounting frame 41. Multiple sets of rubber rods 43 are provided on the outer side of the two sets of rotating shafts 42 located inside the housing 1. Synchronous pulleys 44 are provided on the inner side of the two sets of rotating shafts 42. A synchronous belt 45 is installed between the two sets of synchronous pulleys 44. One end of one set of rotating shafts 42 penetrates the mounting frame 41 and is driven by a motor 46.

[0035] In a further preferred embodiment, the rotating shaft 42 is driven by the motor 46, and the two sets of rotating shafts 42 rotate synchronously under the action of the synchronous pulley 44 and the synchronous belt 45. This causes the rubber rod 43 on the rotating shaft 42 to agitate the impurities in the fixed frame 51, preventing the impurities from accumulating in one place and ensuring the filtration effect of the filter screen 12 on the sewage. At the same time, the synchronous pulley 44 is a synchronous pulley with toothed grooves on the outside, and the synchronous belt 45 is a synchronous belt with teeth on the inner wall, ensuring the transmission effect.

[0036] It also includes a locking mechanism 6, which includes a pressure plate 61 and two sets of guide rails 62. Both sets of guide rails 62 are fixedly connected to one side of the housing 1. One side of the pressure plate 61 has a guide groove 63 for mounting the guide rails 62. The lower surface of the pressure plate 61 is provided with a conical surface 64. The other side of the pressure plate 61 is fitted with a locking bolt 65. One side of the housing 1 has multiple sets of screw holes 14 for tightening the locking bolt 65. The pressure plate 61 slides on the guide rails 62 through the guide groove 63, thereby making the conical surface 64 contact the sealing plate 52, thereby pressing the sealing plate 52 with the pressure plate 61. The locking bolt 65 is screwed into the corresponding screw holes 14, which facilitates the fixing of the pressure plate 61 and ensures the stability of the installation of the detachable mechanism 5.

[0037] In use, wastewater enters the tank 1 through the inlet pipe 2. After being buffered by the first inclined plate 7, the wastewater falls onto the filter screen 12 of the upper detachable mechanism 5. The wastewater filtered by the upper filter screen 12 falls onto the filter screen 12 of the lower detachable mechanism 5. After further filtration by the lower filter screen 12, the filtered water falls onto the guide plate and is discharged through the drain pipe 3. When it is necessary to disassemble and clean the upper filter screen 12, the upper locking mechanism 6 is released, and the fixing frame 51 is pulled out of the support frame through the handle 53. At this time, the wastewater falls onto the second inclined plate 8 under the guidance of the first inclined plate 7. The wastewater falls onto the lower filter screen 12 for impurity removal, achieving a continuous sludge removal effect. At this time, the push block 13 is pushed, causing the filter screen 12 to loosen in the slide groove 54. The filter screen 12 is then pulled out of the slide groove 54 by pulling the push block 13. During the extraction process, the fixing frame 51 scrapes off the impurities on the filter screen 12, further improving the cleaning efficiency of the filter screen 12. The detachable mechanism 5 is then installed in the housing 1 and secured by the locking mechanism 6. When the lower filter screen 12 needs to be cleaned, the disassembly steps of the upper filter screen 12 are repeated, improving practicality.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
